Application filed March 17, 1911.- Serial No. 614,993.

To all ywhom t may concern:

Be it known that I, Fnnnnnicit A. HART, a citizen of the United States,residing in Hartford, inthe county of Hartford and State of Connecticut,have invented certain new and useful Improvements in Combined Type-llvriting and Computing Machines, of which the following is aspecification.

This invention relates generally to that class of combined typewritingand computin g machines .illustrated and described in my application No.466,836, filed December l0, 1908, and also in the British Patent No.3390 of 1912.

According to the disclosure in said application and patent, the generaloperator of the computing mechanism when actuated also controls thereturn of the typewriter carriage.

According to the present improvements, I emplo7 a motor for operatingthe general operator and returning the carriage, and so arrange theparts that upon the writing of any figure in the units place in acolumn, the carriage is connected to the motor and at the same time thegeneral operator is given a stroke` so that the return movement ofthecarriage takes place at the same time that the computing` wheels arebeing rotated.

The present improvements may be carried out in a machine having either asingle computing head or a pluralityof computing heads. and in thelatter case adjustable devices may be set to provide for the operationof thc computing mechanism and return of the carriage only at thewriting of a character in the units place in the last column on the worksheet.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Fig. ll is a top plan view, showing a plurality of registers.

A continuously running electric or other motor l is provided with a mainshaft '2. the latter connected to a sha-ft 3 by means of a safetyfriction clutch. This clutch may comprise a disk 5 having a hub keyed tothe shaft 2, a friction disk G being loose on said hub; another frictiondisk T being confined between disks 5 and G. An arm S fast onshaft 3 isbent over at 49 to be engaged and driven by a lug 10 on disk G. Acompression spring ll is coiled around the hub 4, and adjusted by a nutl?. to detercasing 19.

mine how much of a load the clutch will carry without slipping.

A rack 13, forming part of a rack frame,

is movable forwardlyand backwardly in the base of the adding machine,and performs Uf shefinal portion of the computing loperation. This rackframe is reciprocated Vintermittently by the constantly rotating 'shaft3, by means of a clutch mechanism;

fsaid'frack frame being connected to a crank shaft to be driven thereby,and the crank shaft being connected by a worm gearing to said shaft 3,as will presently be set forth.

Upon the rack frame is secured a .yoke or carrier 14, in engagement withwhich is the upper end of an arm 15, provided on a i cross head 16,which moves forwardly and backwardly,or from left to right at Fig. 1,

so as'to reciprocate saidi-ack frame 13; said cross head being carriedon a horizontal *slide 17. which works vin bearinOs 18 on a C Thisslide` reciprocated by means of a crank fixed on a horizontal shaft 24;said crank carrying a slide block 'l workingA in a groove 27 in thecross heatl- Looseon shaft'24 is a worin gear '30,

-i'neshingfwith a worin 31, the latter fixed on sha ft y ,u tating.

'lhewoifiii wheel 30 is -connectible to shaft 24 to turn the samewhenever it is necessary to reciprocate the rack frame 13 to complete acomputing operation; and at the conclusion of said reciprocation, saidyworm wheel 30 is automatically disconnect- *edV from the shaft 24, axndthcklatter comes to a stop, while 4the motor 1 continues to rotate.

Fixed to shaft 24 is a. cup member 32 of a clutch and fixed to thehub ofworm gear 30 is a collar 33. Running on thisA collar and adapted toengage' the inside of a cylingear 30. I a i The clutch roll is shiftable between grip- A ping and releasing positions in the pocket 35bv means of a ring or disk 36, which rides loosely on the collar 33within cup 32, and which is cut awayat oiieplace to receivethe roll 34,so as to engage the roll on both sides thereof.

3-'S,o that the worm wheel 30gis conf ber.

the reciprocation of the rack frame.

Rotation of ring 36, therefore,' 'shifts the roll. Against said disk 36bears Y' ne end of a compression spring `38, which l'ris-fic'onfinedwithin-a pocket 37. formed in said disk, the other end of said springbearing against a stop 39 secured to the inner side of the clutch cup.The pocket 37 is of sufiicient length to permit a movement of the diskor ring 36 without interference from the stop 39. The spring tends toturn the disk 36 with the roll 34 in a direction. to lock together theclutch cup with lthe bearing collar to cause shaft 24 to rotate withgear 30. In other words, said spring tends normally to close the clutch.Normally, however, said disk 36V' is restrained from causing the roll tobind; or in other words, said disk is normally held in clutchreleasiiigposition.

For this purpose, there is provided a pin -or latch` 40, normally inengagement with a lug 41 provided'upon releasing disk 36, said lugprojecting through an opening in the clutch cup. When shaft 24 is to beclutched to the gear 30, the latch 40 is raised to release lug 41,whereupon spring 38 throws disk 36, together with roll 34, thus lockingthe clutch cup and the shaft 24 to the rotating worm gear 30. The'pin 40is automatically dropped again into the path of lug 41, so that at thecompletion of a single revolution of the shaft 24, the latter is againunclutched from the worm gear 30.

The rack frame 13 is caused to reciprocate after the numeral keys o'fthe typewriterlhave been operated toset up a num- This rack frameoperates to turn the computing wheels to ,different extents, dependingupon the key operated. It is necessary, therefore, in 'some cases, forthe described clu'tch to operate after each number is written on thetypewriter; and while the present improvement relates particularly tomeans for securing such operation automatically, or without attention onthe part of the operator, still I will first describe means ,whereby theoperator mayl depress a special key to operate said clutch, and causeSaid key vis designated as 42, and is mounted on a stem 43 pivoted atits lower end to a lever 44, fulcrumed at 45 upon the machine frame.v

-Said lever 44, in turn,- depresses a cross lever 46, which is pivotedat 47 to the framework, and at its other end engages a notch 48 formedin the top of the trip pin or latch 40, so as to cause or control the upand down movement 'of said latch, wherebyl the clutch is caused to openand close. The lever 46 is provided with an adjustable end or arm 50,upon which the key lever v `42 bears; this part 50 being adjustable byscrews 52, thereby securing accuracy of adjustment and movement of theclutch-con-` trolling mechanism.

Depression of the key 42 carries down the lever 44, the latter rocks thelever 46 about its fulcrum 47, the other end of the lever lifting thelatch 40 away from the clutch lug 41. The operator immediately releasesthekey 12. which is returned to normal position by a. spring' 51. Themovement of the key is limited by a pin 55 within a slot 56 in the keystem. The lever 16 has a returning spring 57.

The typewriter includes the usual set of type-operating keys, includingalphabet kevs and also including` numeral keys S8 mounted on levers 8Sand connected by bell cranks 89 to type bars 90, which are thrown backagainst a platen 91 mounted on a carriage 92. The carriage ispower-driven. as usual. and vhas-a rack 97 meshing with a pinion86connected with an.escapeinentwheel 85, the latter` controlled by dogsS1, operated y a universal bar S3, which is actuated by the type bars,so that whenever any type key is actuated, the carriage 92 is caused tofeed a.. letter space.

Fastene'd at the back of the 'carriage 92, are bra'ckets 93, carrying arack J1, to receiver-adjustable cams or tappets 95. Yhenever*anyztappenduring the travel of the carriage, passes beneath the set of jacks 96,it raises the forward ends of the jacks in succession, turning each onits pivot'97, and depressing its rear end to press down thecorresponding one of a setl of wires 98. These' wires are connected attheir lower ends to levers 99 on a fulcrum rod 100.

Each lever 99 raises one of a set-of linkages 101, each linkagehaving apin 102 to lift the rear end of. a rack 103, the forward end of whichmeshes with a pinion 101 connected to a computing wheel 105. Each rackcarries a set of pins 106, and one of these is depressed by the operatedtype key S8; each key having a stem 110, for this purpose. to depress acrank 112, fast to a shaft 113, which is connected to a linkage 111, todepress one of the pins 106 upon the lifted rack bar 103; there beingone linkage 111 for each key, each linkage being` in position to depressa corresponding pin 106 on whichever rack bar is lifted. Thus it will beseen that the pins `on the rack bar 103 form in effect a register onwhich items are registered prior to being carried into the computingwheels. After the keys S8 are manipulated to write a number, and thecorresponding racks 103 accordingly elevated as the paper-carriagefeedsalong, and certain pins 106 thereon depressed, there must be causeda reciprocation of the rack frameI 13. This frame usually includes apair of arms 115 connected by a transverse horizontal bar 116, which isin position to engage all the displaced pins 106, and to givecorresponding forward endwise movements to their racks 103, therebyturning the computing wheels 105 accordingly; the return movements ofthe racks not turning said wheels, however, because of a pawl-andratchetconnection (not'shown) between said wheels and their drive pinions 101.Pinions 'near its upper end `on an 116@ meshing with racks 13, are alsoin mesh with segments 116b fixed on rock-shaft 116C.

This computation movement of the rack frame or so-called generaloperator7 13 is secured automatically, at; the completion of thewritingl of a number, that is, without the necessity' of depressing thekey 12, and without the necessity of the operatorl keeping` the matterin mind.

For this purpose, at the left-hand end of each group of jacks 96 isplaced a supernumerary jack 11T, connected bv wire 9S to a bell crank123. pivoted on shaft 100 at the left-hand end of the gang ofllevers 99.The bell lcranks 123 are connected by llinks 128 to arms 121, depending`from a horizontal transverse rock shaft 125. The middle Vlink 12S has aforward extension 12S?, carrying a pin 129,v which at the movement ofany of the bell-cranks 123, is thrust forwardly against a link 130, thelatter pivoted arm 113, for the purpose of vibrating the latter.

This link 130 is normally idle, but is capable of swinging to positionto form an interponent or movement-translnitter between said arm 113 andan arm 132, which latter is power-driven and constantly vibrates'up anddown. so that said arm 113 is .vibrated, together with rock shaft 111 onwhich it is fixed. and an arm' 11T on said shaft 111 swings down tooperate the lever 16, which it will be remembered. lifts the clutchlatch 10 so that the shaft 21 becomes clutched to the gear 30, and hencethe rack frame or operator 13 is caused to reciprocate.

The arm 132 is kept in constant vibration by means of a follower 131,the lower end whereofis pressed by a spring 135 against a wheel 133,which `is in the nature of a .star wheel or cam wheel, consisting of asuccession of depressions and elevations. This wheel 133 is fixed t'othe worm gear 30, and hence the arm 132 is constantly vibrated up anddown while the motor 1 is in operation. The arm 132 is adjustablyconnected to the follower 131 by means of apivot 132a and adjustingscrews 1321, as seen at Fig. 1.

It will be understood that when the pin 129 thrusts forwardtheinterponent 130, the latter is swung to position over the arm 132, asseen at F ig. 1, and the latter, when rising, thrusts up the interponent130, and swings arms 113 and 117, and tripsthe clutch, as alreadyexplained; so that the computing operation is completed automatically asthe paper carriage 92 of the typewriter completes the letter-spacingoperation which is occasioned by the return to normal position ofthetype-operating numeral key 88 which was employed to write in the unitsplace.

dependently adjustable along the rack bar 94 on said paper carriage 92.It will be understood from this that the general operator, 13 will beactuated each time that a-key 88is operated-to calculate a number in theunits place, in any of the three groups of computing mechanism; saidgeneral opera-- tor 13 being therefore actuated three times during eachline ofwriting, assuming that three columns are being written at thesame time -unon the Work sheet.

Provision is made for silencing anyone or more of the jacks 117 at Figf,as will be understood by reference to Figs. 7 to 10. Each supernumeraryjack 117 is pivoted upon a pin 148, which is formed eccentrically upon astub-shaft 149, which. is journaled inf the jack frame 150 in line atFig. 7 with the pivot 97 of the denomination jacks y96. Upon eachstub-shaft is provided a button 151, whereby the pivot 146 may berotated from its normal depressed position at Fig. 8 to its elevatedposition at Fig. 10, the jacks 117 in the former case being held down inworking position, and in the latter case `being held up clear of thetappets 95, so that the actuation of the general operator 13 will notoccur. The buttons are independently movable, so that the operator mayhave such `jacks 117 in or out of use as he may desire. Each stub-shaft149 may be held in either of its Fig. 8 and 10 positions by means of aspring 152 and detent pin 153, the latter engaging 'a depression 154 inthe stub-shaft.

In Figs. 1a and 1b, l illustratel the mechanism for controlling theamount of return movement given to the carriage. The shaft 116c extendsthrough the right end of the frame, and carries a rigid arm 155, andthis arm carries a loose pinion 156, which rolls freely on a gear wheel157, which is loosely mounted on the shaft.

As the arm 155 swings around, the pinion 156 comes into contact with thepinion 158, and their teeth lock into each other, and lock themselves tothe gear 157, so that after this engagement, tated. Thislockingeffectwill be evident from the fact'y that when the pinions meshtogether,v the tendency of the further movement ofthe arm locks them tothe gear. U

The rotation of the gear 157 is lmparted through a pinion 160 to apulley 161, around I In the returning' vmovement the arm 155 swings'inthe directhe gear 157 will be ro- 155 is to rotate the pinions inopposite directions, and this, of course,

vwhich the returning band 162 passe'slgand from this point the returningband :passes `up over a suitable guide pulley 163, heyend which it isattached "to thecarriage. theband 162 may be attached to any suitablepoint in the carriage, it is preferably -attached to the line-spacelever 166, so that the platen will be spaced up as usual for a new lineat the Sametime that the carriage is returned. ltwillbe evident that theonly effective partfbfthe movement of the arm 155 in returning: thecarriage,

that which takes place'aft'er it picks up? the interponent arm 159, andby adjusting the interponent arm to any position desir given to thecarriage.

It will be seen that when the parts are in any amount of return-movement may be the Fig. 8 position, the carriage will be returned andthe operator automatically `actuated at the completion of the writing ofthe number on the work sheetgbut-.at any time any of the buttons151 atFig. 6may be turned to set the jack or jacks 117 to the idle positionseen at Fig. 10,l and at the completion of the writing of the numbers inthese columns, the carriage will .not be returned automatically nor willthe computing machine actuator be operated.

By reason of the fact that provision is made for returning the carriageconcomiV tantly with the computing operation, it is evident that in thestructure disclosed, the jacks 117 have the function ofcarriagereturning members as well as that of computation-controllingmembers.

Variations maybe resorted to within lthe Y carriage, type-operatingnumeral keys, a
